I was at the Victoria .Net SIG meeting last night and had the pleasure to hear David Burela give the same presentation that won him the Imagine CUP for Australia. The product that he and three other students created was called SOAK and is:
SOAK is an integrated software and hardware platform with the aspiration of helping farmers achieve sustainable use of their land. This is achieved through the integrated use of environmental sensing, rich visual front ends to display the information to the farmer, and a subsystem which controls farm equipment such as sprinkler systems
I was blown away by the quality of the presentation and can see why they won. It is good to see quality people like David coming through the system and providing some competition for us old guys.
